3.3.8 Eradicating radar interference
Weak echo images from hazardous objects such as other vessels may also be
rejected when using the interference rejection function.
When observing radar beacons or SART signals, make sure that the interference
rejection function is disabled.
Radar interference refers to the phenomenon by which microwaves transmitted by a
third party radar is picked up directly by the ship's scanner unit and is displayed on the
PPI screen.
